CPerfMon on Windows 2003


I developped an application exposing performance counters using the ATL
classes CPerfObject and CPerfMon. It works fine under Windows XP but the
counters are missing in the Performance Monitor on Windows 2003.

Even the Microsoft sample application PerformanceScribble exposes the same

Does anyone know why the ATL classes don't work under Windows 2003?

Thanks in advance,
